通过X射线光电子能谱(XPS)、椭圆偏振原位测试考察了氯化2,3,5-三苯基-2H-四唑(TTC),2,4,6-三(2-吡啶基)-s-三嗪(TPT)分子在1mol/LHCl中对碳钢表面的缓蚀作用,并从微观上对二者的缓蚀机理进行探讨.XPS测试结果显示,由C,N元素的1s特征峰产生的化学位移及其积分峰面积表明TTC,TPT分子在金属表面产生了有效抑制腐蚀的保护层;由椭圆偏振原位测试并结合动电位极化曲线测试,考察了TTC,TPT分子对金属表面腐蚀反应的抑制程度,并得到了相位差等参量,结果表明二者在金属表面形成了具有缓蚀作用的覆盖层.
The effects of 2,3,5-triphenyl-2H-tetrazolium chloride (TTC), 2,4,6-tris (2-pyridyl) -s-triazine (TPT) molecules on the surface of carbon steel in 1mol / LHCl, and the corrosion inhibition mechanism of the two were discussed microscopically.The XPS test results show that the 1s features of C and N elements The peak chemical shift and its integral peak area indicate that the TTC and TPT molecules produce a protective layer that effectively inhibits the corrosion on the metal surface. The results of the ellipsometry in situ and the potentiodynamic polarization curve test show that the TTC and TPT molecules affect the metal The degree of inhibition of the surface corrosion reaction, and the phase difference and other parameters have been obtained. The results show that both of them form a coating with corrosion inhibition on the metal surface.
